With headers how loud is the RB duals?
Also, does anybody sell any true dual setups? All i've seen are the ones with the Y-pipe.

If I had RB Header and RB cat replancement and presilencer with stock catbacks, stock muffler (I would replace with Bolra catbacks ASAP when i got more money) but how loud would that be?

So are you guys telling me that with the rb headers connected to the cat then connected to Apexi N1 duals will be way to load and be a bad choice. I don't want them extremly load.

HAHAHAHA or you could do what I did, I have the full RB setup up header back. you just through the biggest sub box you can find in the back, the 15 hp you gain in exhaust you lose in weight. and you don't have to here your annoying 95db exhaust 'cause you have a 140db stereo.....

Well i guess its the nature of the rotary to sound like a lawn mower when idling and sound like a ferrari when revving up. But lemme ask this just so that its covered: Exactly how crappy are the stock mufflers? Is it possible to run some kind of weird RB headers, with cats and stock duals setup...or am i just being an idiot? Of course if the stock duals were to be used, the piping diameter would be increased. I just wanna know if the stock mufflers can be used..or maybe stock turbo mufflers or something. Ideas anyone?

Yes, that is possible. I am planning on doing just that: using a Racing Beat collected header, stock main cat, and stock cat-back. The main cat is slightly shorter than the RB presilencer (the RB collected header + presilencer are designed to replace the stock manifold and all cats, then bolt up to the stock catback) but any length that I may need to add, in order to get the exhaust tips to look right at the rear bumper openings, will be done with two glass-packs welded into the straight segments of the "y" pipe. These will also help reduce the noise level a little more, and are very cheap ($20 each).

Good stuff...Who all loves their headers? Its would be interesting to see before & after HP readings...

All in all is it worth getting the RB headers on my car with the N1 duals. If it sounds good I don't care how loud it is. It should also give me a good hp increase.

I'm going to a Rx-7 garage and checking the price of the rb headers this weekend. Not sure how much its going to cost, what is the price for instalation do you guys think.

dont get polished mufflers...you stand less of a chance of improper equipment tickets.

i want to no will those RB headers work with a bonez super flo cat system

ibemrzach

ha. i'm gonna put the rb header on my rx7.com racepipe with borla dual exhaust setup in about a week and a half. don't call me, i won't be able to hear anything you say.

Yeah i have a header with a straight pipe and an imitation N1 style POS muffler and its about as loud as just the header and straight pipe with no muffler. those Rice mufflers dont do **** for sound deadening really. Cant hear the radio, cant hear fire trucks nor trains.

It won't sound like rice will it with the RB headers and the N1 duals. I hate the rice sound.
